President Donald Trump's official Twitter account, @POTUS, was linked to a potentially insecure Gmail account until mid-afternoon Thursday.

Earlier on Thursday, Alex Zalben, managing editor at TV Guide, discovered that Trump's account was linked to Gmail -- which would potentially leave the account vulnerable to hackers. (CNBC was able to confirm Zalben's findings at the time.)

As of mid-afternoon, the account was changed, and is now linked to two different emails, likely official White House accounts.

This comes as The New York Times reported Trump is still using his Android phone device, despite objections from at least some of his aides. A Twitter account linked to a personal email would almost certainly not conform to federal security standards.

During last year's presidential campaign, Democratic candidate Hillary Clinton was heavily criticized from many corners for using a personal email account for official State Department business.
